Women in African History and another book about Wangari Matthai!

I ordered Wangari Matthai, The Women Who Planted a Million Trees yesterday and can’t wait to see how it compares to the other four books about Matthai. Ellen, the bookseller, told me that Matthai is included in the UNESCO Women in Africa series. Please let me know if you have used this website!http://en.unesco.org/womeninafrica/
